Svbony SV172 - 430 mm Dew Heater Strip with PWM Function - W9132D

At 430mm, this dew heater strip is ideal for larger lenses or optical tubes, offering full coverage for better protection.

Features a PWM (Pulse Width Modulation) function for precise temperature control, preventing dew formation without overheating.

Built with high-quality materials, this dew heater strip is waterproof and durable, ensuring reliable performance in various weather conditions.

Simple to install and use with a variety of power sources, making it ideal for long outdoor observation sessions. 

Features

• Compatibility: designed for astronomy telescopes and compatible with DSLR camera lens, protecting optical devices like telescope and camera from fogging or freezing

• Energy-saving: PWM technology allows for adjusting the working cycle and pulse width of the heating tape according to the needs, providing heat only when necessary. This reduces energy consumption and saves electricity.

• Precise control: it control enables precise temperature regulation of the heating tape to meet specific requirements. By changing the pulse width and cycle, high-precision temperature control can be achieved, avoiding overheating or excessive cooling.

• Extended lifespan: due to the intermittent operation of PWM heating tapes, their lifespan is longer compared to continuously operating regular heating tapes. Additionally, the stable temperature reduces the risk of equipment damage caused by temperature fluctuations.

• Efficiency: PWM heating tapes can quickly respond to temperature changes and reach the desired temperature in a shorter time. This fast response and efficiency improve heating effectiveness and reduce energy waste.
